2lnx + ln(8 + x) = ln(40)
2lnx + (8 * ln + x * ln) = ln(40)
2lnx + (8ln + lnx) = ln(40)

Reorder the terms:
8ln + 2lnx + lnx = ln(40)

Combine like terms: 2lnx + lnx = 3lnx
8ln + 3lnx = ln(40)

Reorder the terms for easier multiplication:
8ln + 3lnx = 40ln

Solving
8ln + 3lnx = 40ln

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-40ln' to each side of the equation.
8ln + -40ln + 3lnx = 40ln + -40ln

Combine like terms: 8ln + -40ln = -32ln
-32ln + 3lnx = 40ln + -40ln

Combine like terms: 40ln + -40ln = 0
-32ln + 3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-32 + 3x) = 0
